Patent GB-687796-A (GB)
Title: Device for measuring the high frequency resistance of oscillatory circuits in radio apparatus
IPC: G01R27/26
Filed: 1950-10-11
Abstract: 687,796. Resistance measurements. BERREKLOUW, D. Oct. 11, 1950 [Oct. 12, 1949], No. 24808/50. Class 37. The high-frequency resistance of an oscillatory circuit in a radio apparatus is measured by providing a potentiometer or voltage regulator 4, Fig. 1, between a modulated signal generator 2 and the tuned radio apparatus 1 under working conditions and observing the difference in the setting of the regulator 4 with and without a standard impedance 7, Fig. 2, connected across the apparatus under test. Screened cables 3, 6 connect the generator 2, regulator 4, and radio receiver 1. The regulator 4 has a three-position switch 10, the first position connecting the regulator between the generator and the receiver. In the second position the regulator 4 is switched out and the signal generator 2 is directly connected to the receiver 1 to allow the receiver to be trimmed. In the third position the generator 2 is disconnected in order to test whether it is radiating directly to the receiver. The dial 5 of the regulator 4 has two scales running in opposite directions. A meter 11 is connected across the output terminals of the receiver 1. For measuring a large high-frequency resistance the receiver 1 is tuned and the voltage regulator or potentiometer 4, a fixed portion of which may be permanently switched in, is set at the beginning of the scale appropriate to the measuring range. The signal strength of the generator 2 is adjusted so that the meter 11 is in the middle of the scale. The terminal 9 of the impedance 7 is connected to the frame of the receiver or with the lower end of the circuit to be measured and the pin 8 is connected to the upper end of the circuit, e.g. at one of the points 12, 13. The deflection of the meter 11 decreases and is brought to its orignal value by adjusting the voltage regulator 4. The high-frequency resistance is then read directly on the dial 5. For measuring a small high-frequency resistance the regulator is set at the terminal position of the second scale, which runs in the opposite direction to the first scale, and the impedance 7 is connected across the circuit to be measured. The generator 2 is adjusted to bring the reading of the meter 11 to mid scale and the impedance 7 is removed. The deflection increases and is brought to its original value by adjusting the dial 5, on which the resistance is then read directly. The voltage regulator is calibrated according to the formula R x =Z(n-1), in which Rx is the highfrequency resistance to be measured and n is the voltage ratio necessary to keep the voltage constant over the circuit to be measured, i.e. the output potential of the receiver after switching in or out the standard impedance 7. A direct reading of the high-frequency resistance is then obtained.

Title: A transportable mobile power unit for moving railroad or railway freight cars and wagons and other vehicles
IPC: B61J3/00
Filed: 1945-09-27
Abstract: 600,130. Tractors. HERSCOVITCH, W. Sept. 27, 1945, No. 25158. Convention date, Sept. 27, 1944. [Classes 79 (i), 79 (ii) and 79 (iv)] A mobile power unit for moving railway trucks or other vehicles comprises a frame mounted upon at least two transport wheels which are arranged in longitudinal alignment, lifting mechanism, the base of which is rigidly secured to the frame at a point between the transport wheels and which is adapted to lift a truck or other vehicle, in order to increase adhesion pressure of the transport wheels, and means for driving at least one of the transport wheels. As shown, the unit comprises a frame 2, supported at one end by a driving wheel 16 and at the other end by a second wheel 32. A jack 36, enclosed within a housing 34, is mounted rearwardly of the axis of the wheel 16 so that the weight of the lifted truck increases the adhesion pressure between the wheel and the rail. The driving wheel 16 derives its power from a petrol engine 57, through a gear-box 48 and chain and sprocket drives. The axle 15 of the driving wheel is driven at one of two speeds through sprockets 25, 23, which are free to revolve on the axle. A pair of sliding dog-clutch elements 22, 24 on the sprockets 23, 25, adjustable by levers 82, 83, enable the operator to engage that sprocket corresponding to the speed of drive he desires. The engine is connected to the gear-box by a friction clutch 67, 68 which is controlled by a grip 77 on the handlebar 8. The throttle control 64 is mounted on the handlebar 9. In operation, the jack is made to lift one corner of a railway truck, thereby transferring weight to the wheel 16 to prevent slip, low gear being engaged until the truck is moving sufficiently fast to engage high gear. As an alternative to moving trucks in this manner, the unit may be anchored to the rail with the wheel 16 clear of the rail. The freight is then hauled by cable wound on a drum 18, which drum is continuously driven by the axle 15 of the driving wheel 16. An outrigger, Fig. 4, comprising members 92, a wheel 16, driving shaft 93 and a jack 36 may be attached at the front and to one side of the unit. The shaft 93 has a coupling 94 by which the shaft 93 and axle 15 may be connected.
